A Script on This Page Has Stopped Responding

I am still baffled by this huge lag, WA Docs state I can map from a recordset and makes no mention of limitations or lag of any kind.

I have been tracking the average time of the recordset query and that is roughly 31 milliseconds for it to pull all of the records, however the map takes so much longer to generate and that's after the script warning.

The only way I have seemed to be able to speed it up is by limiting the number of records returned to under 10 and that renders the recordset feature pretty useless.

I know that it takes time for google to plot these addresses but this seems way over the top.

Any thoughts on this is greatly appreciated.

Thanks,
Paul
